' Genoa,inthe'county-ofNance and State 'of Nebraska, have invented :a 'newan'duseful Support for I'IeadSets, of which lthe-follow'- ing isa specilication This inventionv relates to head-sets forradio receiving instruments and the like, and especially to means for supporting the ear pieces.

One of the chief objections to the headsets now commonly used is the considerable pressure exerted against the ears, which often vcauses great annoyance, pain and even injury to the user.

The general ob'ect of the present invention is to provi e an improved support,

which is simple and inexpensive 'in its con-` struction, adapted to. support fory yvertical adjustment any yof the ear pieces now used,

and which may be so adjusted as to lessen or entirely remove the pressure-from both ears or from one ear only.

The nature yof the invention and its advantages will be apparent from the following detailed description taken in connection with the accompanying drawing, which illustrates the invention in its preferred form.

In the drawing:

Figure 1 i-s a front view of the invention, partly in elevation and partly in section.

Figure2 is a sidefelevationof one side of a head set having my invention applied thereto.

Figure 3 is a perspective'detail view of the block for supporting theear piece Aand the parts associated therewith.

Figure 4 plate and brackets between which the block is mounted.

The invention is adapted to be applied to a head-setv having a head band composed of one or more resilient bowed members 10, adapted to span the head of the user. pressure plate 11 is secured at each end of the band, and is preferably provided with a lining 12 of felt or the like, althoughthe lining is not .essential to the invention. As

shown in the drawing, the platey 11 is provided witha number of'holes 13 to vwhich the lining may be secured by sewing, as indicated at 14. A pair of brackets 15 and 16 are riveted or otherwise secured to the outer side of each plate 11 in s aced relation to each other, and Ione of the rackets, as 16, is

'providedwith a boss 17 internally threaded 'toreceive the threaded end v18 'of a. thumbr screw -19.-A supporting block' 20V is piviotally mounted at 4its inner. end on the lscrew vv19 between the opposed faces ofthe brackets' 15 and 16, and the thumb screw 19 is formed f '.witha shoulder 21uengaging the-outer face f of the bracket 15. Either 'thefbrackets.lor the pressureplate 11, or both, are somewhat resilient, so that by tightening the'thumb screw 19, the opposed bracket arms may be drawn togetherf into clamping relation to the block 20 to secure the same in any position to which it may be adjusted.

Each ear piece 22 is pivotally supported in a yoke 23, provided with an upwardly extending stem 24. Each block 2O is provided lwith'a bore 25. in whichthe steml 24 is vertically adjustable. f A set' screw 26, or other suitable means, may be'fprovided by means of which the stem 24 may bev readily secured in its adjusted position. The 'upperl end of the stem 24 will ordinarily be pro-v vided with a knob 27, which may be detached for removing the stem 24 from the member or inserting'it therein. Y

In the use of thehead set, the same is retained upon the head by the pressure of the plates 11 against the head above the ears, and the supporting blocks 20 may be independently adjusted about the thumb screw 19 as an axis, so that either one of the ear pieces 22 may be held against the ear with as much orv as little pressure as may be convenient. Thel stems 24 may be adjusted vertically in the bores'25 to bring the earl pieces at the proper height to secure -the bestresults.y

. The invention is adapted to beattachedto any head-set now in use. In most of these 'head-sets the ear piece is supported by a stem, and to apply the invention thereto, it is only necessary to remove the knobs 27. The invention is simple in its construction and consists of a minimum number of arts, which may be manufactured .at a sma l expense. The ear pieces may be adjusted to any pressure, and positively held in such position' merely by turning the thumb screws 19.

While. I have shown in detail one embodiment of the invention, it is obvious that various modifications may bemade in the form, size, proportion and arrangement of no the various arts without departin vfrom the salient eatures of the mventlon, or sacrificing any of its advantages. It 'is my desire, therefore, to include all such modifi- What is claimed is 1. In a support of the character described, the combination of a head band having a pressure p-late secured to each end thereof, a block mounted for pivotal adjustment about an axis substantially parallel to each plate, clamping' means for securing the block in its adjusted position, said block having a bore extending' Jfrom top to bottom thereof, and means cooperating' with said bore for adjustably securing` the stem of an ear piece.

2. In a support of the character described,

- the combination of a head band having a pressure plate at each end rthereof, a pair of anole brackets secured to the outer face of eaei pressure plate and having opposed clamping surfaces Which are substantially perpendicular Vt-othe pressure plate, a screw traversing the opposed portionsl of the brackets, a block pivoted on the screw, theY latter ybeingv operable to clamp the block between t-he brackets in any position to Which it may be adjusted, said block having a bore extending'4 from topto bottom thereof 'for receiving the stem of an ear piece, and means cooperating with said bore for adjustably securing' said stem.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature.
